To ctZZ whom it may concern.-

Be it known that we, HARRY N. CovnLL. of the city of New York, boroughof Brooklyn, county of Kings, and State of New York, and CHARLES A.BAECHTOLD, of Westfield, Union county, and State of New Jersey, haveinvented a new and useful Improvement in Reversible Driving Devices, ofwhich the following is a specification.

Our invention relates to an improvement in reversing driving mechanisms,and comprises novel features, which will be hereinafter particularlypointed out in the claims.

We have herein shown our device as applied to a winch-head in suchmanner that it may be reversed in direction of rotation, as desired. litis, however, to be understood that our device may be used for connectinga shaft rotating constantly in one direction with any other device whichit is desired to turn in both directions.

Figure 1 shows a longitudinal section of our device as applied to awinch-head. Fig. 2 is a section taken upon the line 2 2 of Fig. 1. Fig.3 is a plan and partial section of a modification of our device.

The drawings accompanying herewith illustrate the form of constructionnow preferred by us, but not the only form of which we are aware inwhich our invention may be embodied. The construction of this form willnow be described.

In the drawings, A represents the shaft, which is constantly rotated inone direction. In the case of a winch-head as applied to ahoisting-engine, for which use our device is particularly designed, thisshaft would ordinarily be the shaft of one of the hoistingdrums. It willbe so considered and described herein, although it is to be understoodthat our invention may be employed independently of ahoisting-drum. Tothis shaft is keyed or otherwise fixedly secured a sleeve B, which isprovided near one end with aradially-extending flange B, one face ofwhich is provided with teeth, forming a bevel-gear B Loosely mountedupon the end 6 of the sleeve B is a winch-head C, which is secured inplace thereon by means of a washer'J and a bolt J, which screws into theshaft A. Loosely mounted upon the opposite end of the sleeve B or uponthe section 6' thereof is a member which consists of a radial disk D,terminating at its outer edge in a circular ring D, thus forming a hoodwhich incloses the operating mechanism and acts as a pinion-carrier. Theinner face of the winch-head O is provided with teeth, forming abevel-gear O, which corresponds in size and is located opposite thebevel'gear B Rad ially journaled upon shafts l, which are secured to thehood D, are beveled pinions I, which mesh with the two gears B and O.The outer periphery of the hood is provided with a friction-surface badapted to be engaged by a frictionbrake of any character. The brakeherein shown consists of a band E, which has its ends secured to pins inand carried by a lever K at unequal distances from a central shaft K. Adisk F is secured to turn with the shaft A, but to slide longitudinallythereon, and carries one half of a friction-clutch, the other half beingcarried by the disk D. The friction-clutch may be of any desiredconstruction, the construction herein shown consisting of annular disksor rings G and Gr, secured, respectively, to the disks D and F. Anyother well-known form of friction device may, however, be substitutedtherefor, as the employment of the particular kind of friction deviceillustrated is not essential to the success of our invention. The disk Dmay he slid longitudinally of the shaft by any desired mechanism inorder to apply the friction-clutch. If any other form of friction deviceis employed, a suitable applying mechanism therefor would be employed.The mechanism'herein shown consists of two cam-disks H and H,surrounding the shaft, the disk H being held against movement byengagement with the frame of the engine and the disk H being turnableupon the shaft. These two disks are f'zprovided with cam-surfaces it, sothat whenjthe disk H- is turned the disk F will be moyed upon the shaftto engage or disengage the friction-clutch. The disk H is provided withan arm H which is connected, by means of a link L, with one end of thelever K upon the operating-shaft. The connections of the cams and theband-brake with the lever K are such that when one is applied the otheris released. The shaft K may be mounted in any suitable manner andprovided with an operating-handle at any convenient polnt.

From this description the operation of our improvement will be readilyapparent. For instance, if it is desired to have the winchhead C turn inthe same direction as the shaft the friction-clutch is thrown intooperative position and the brake E is taken off the disk, so that thepinion carrying disk and the winch-head will be locked by the action ofthe friction device and will turn the shaft. If it is desired to reversethe direction of the Winch-head C, the friction-clutch is thrown out ofoperation and the band-brake E is brought into engagement with itsbrakingsurface, this holding the pinion-carrying disk stationary, sothat as the sleeve member B turns with the shaft the radially-extendingflange B will turn the pinions about their respective axes, and as suchflange is fast with and turning in the same direction as the shaft thedirection of rotation of the pinions intermeshing with the part C of thewinch-head C will drive such winch-head in a direction opposite, or thereverse of the rotation of such shaft.

In the modification shown in Fig. 3 the winch-head C is not mounted uponthe same shaft as that carrying the reversing mechanism. In this casethe winch-head is mounted upon an auxiliary shaft A and is provided witha radial flange G which is provided with teeth forming a gear which isin mesh with a gear upon the shaft A, carrying the reversing mechanism.As herein illustrated, these gears are spur-gears. the gear C upon thewinch-head being an internally-toothed gear. The reversing mechanismemployed in this modification is similar in construction to that shownin Fig. l. The gear C corre- Sponds with the winch-head (l, as shown inFig. 1.

It is evident that the reversing mechanism may be connected with awinch-head, which is separated from the main shaft A in any suitable ordesired manner. The connections as herein shown are simply given asinstances thereof. o do not, therefore, wish to be confined to the exactform of the device as herein shown, as the same is capable of manyvariations without departing from the spirit of the invention.

Among the characteristic features of our device is the use of two fixedand two loose members upon the revolving shaft and the use therewith ofa single train of gears between the shaft and the winch-head or otherobject to be turned, the support for an intermediate gear of the trainbeing engageable with friction devices, to be either held againstrotation or to be turned about its axis.

One great advantage of our device is that the winch head or. drum beingunobstructed at one end permits a rope being applied or removed withoutdifliculty and enables the strain to be applied to pull upon either endof the rope without reversing the engine. It

is thus well adapted for use upon hoisting-em gines, and especially forthe purpose of swinging a derrick.

We do not wish to be understood as limiting ourselves to the particularconstruction herein shown, butdesire to claim any constructions whichare substantial equivalents or reversals of the construction hereinillustrated.
